AR-10 FDE quad rail

Recommended Posts

I'm brand new to this forum. I have a diamondback firearms AR-10 and it has the keymod handgaurd. I have scoured the internet looking for a quad rail handgaurd in flat dark earth. I hate the key mod I want the full quad rail system. I'm looking for length of 11" or longer. I have the 16" barrel

I have both more K mod than Mlok. Mechanically I can see Mlok being stronger of the 2. Neither is cheap for rails. I'm half dead already if I need a rifle for smashing heads I'll get the Garand. Just my 2 mags

What criteria are you using? The reason I ask is I have seen some variations on the Armalite style that could cause issues getting the right rail. I have two Matrix receiver sets with the Armalite angle cut, one used the Armalite barrel nut thread pattern while the other used the DPMS pattern. Neither one will mate to my AR-10.

These DB10 receivers are exact copies of Matrix Aerospace receivers (and Matrix made all the Ruger SR-762 receivers), and I have an early Matrix with a DPMS-sized barrel threading on it. However, Matrix released them in both thread patterns.

DPMS pattern is 1 7/16" diameter by 16-pitch threading. Armalite AR-10 is 1 7/16" diameter by 18-pitch threading. That's what you need to discover on your upper. The Armalite cut matters - for mating to a lower. In these sets, the threading is what's gonna determine what handguard you need to get, to fit your rifle.

Once you know (and tell us) that information, recommendations will come out...

I found out today from diamondback firearms that it is the 1-7/16 x 16 pitch. I called them and they were very helpful and lady I talked to was super nice and very helpful. She didn't have the answer in front of her but ran around talking to the correct people to find the correct answer for me. I recommend them.

Just seems easier to put whatever attachment you want on and fine tune its position as opposed to having to keep undoing the rail and things seems to be a headache

I got ya, it would be easier if you remove and adjust attachments a lot. I usually put mine back in the same place if I take it off. about all I have thou is a light and QD sling mount. oh and a front grip of some sort.
